This invention relates to snowplows.

An object of this invention is to provide a snowplow designed forattachment onto the front of a tractor and for connection to theelevating means on the tractor, so that the plow will form a clearedpath ahead of the tractor.

Another object of this invention is to provide a plow of this kindincluding means whereby the plow may be angularly adjusted relative tothe supporting frame so that the plow may be mounted on various types oftractors and properly adjusted so that the lower edges thereof will behorizontal when the plow is in lowered operative position.

To the foregoing objects, and others which may hereinafter more fullyappear, the invention consists of the novel construction, combinationand arrangement of parts, as will be more specifically referred to andillustrated in the accompanying drawings, but it is to be understoodthat changes, variations, and modifications may be resorted to whichfall within the scope of the invention as claimed.

In the drawings:

Figure 1 is a plan view of a snowplow attachment for a tractorconstructed according to an embodiment of this invention.

Figure 2' is a detailed side elevation of the device.

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure1.

Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure1.

Referring to the drawings, the numeral l designates generally a framewhich is adapted to be pivotally mounted on a tractor and to ex tendforwardly of the tractor. The frame Ill is formed of a pair of elongatedside bars ll connected together adjacent their forward ends by means ofa connecting bar E2. The rear ends of the bars I! are adapted to bepivotally mounted on pivot members I 3 which are adapted to extendthrough depending supporting plates M which may be fixed to or may beformed as a part of the tractor frame or chassis iii. A pair ofangularly disposed bracing bars I6 are connected between the outerportions of the connecting member I2 and the longitudinal bars I l.

A plow member generally designated as IT is disposed at the forward endof the frame I0 and comprises a pair of forwardly convergent blades l8which are fixed together at their convergent ends and these blades l8are transversely curved with the concave sides l9 thereof foremost.Theforward ends of the frame bars II are pivotally connected to the plowIT by means 'of a pivot 1 Claim. (0]. 37-44) -which engages through 'apair of ears 2! fixed to the rear convex sides of the blades l8 at apoint closely adjacent the point of the plow.

A bracing bar 22 is adjustably connected between the frame ID and thepoint of the plow at the upper end of the point. The bracing bar 22 ispivotally mounted on a pivot 23 fixed between a pair of cars 24 whichare fixedly secured to the point of the plow I I. The bracing member 22extends downwardly and rearwardly and is provided with a plurality ofopenings 25 through a selected one of which a pivot member 28 is adaptedto engage. The pivot member 26 is carried by a pair of ears 21 which aresecured to the transverse connecting bar l2. The outer ends of theblades is are adapted to be braced by means of braces 28 which at theirrear ends are fixed as at 29 to the outer sides of the frame bars II.The bracing members 28 extend downwardly and forwardly and are engagedbetween a pair of ears 30 fixed to the rear sides of the blades l8. Abolt 3| extends through the cars 30 and the forward ends of the bracingmembers 28. There is an adjustable bracing bar 32 for each bracingmember 28 which is pivotally mounted on a. pivot 33 carried by a pair ofears 34. The ears 34 are fixed to the upper portions of the blades IS onthe rear sides thereof and the bracing bars 32 extend downwardly andrearwardly being formed with a plurality of openings 35 through whichbolts 36 engage. The bolts 36 extend through the bracing members 28 asshown in Figure 4.

In the use of this plow the frame I0 is adapted to be mounted at therear end thereof on pivots l3 which are engaged with a suitable portionof the tractor frame. The frame Ill also has associated therewith anelevating or lifting means which may form a conventional portion of thetractor. This lifting means may be either hydraulic or mechanical andsince this lifting means is conventional, it is not here shown. The plowI! is initially adjusted through the medium of the adjustable bracingmembers 22 and 32 so that the lower edges of the blades l8 will behorizontal when the plow is in its lowered position. This plow will forma cleared path for the tractor and while it has been designed forclearing snow, it may be used for moving earth or the like. This plow isdesigned as an attachment for the front end of a tractor and can beeasily and quickly mounted on the tractor and easily and quickly removedtherefrom.

I claim:

A snow plow attachment for the front end of rearwardly therefrom, aplurality of spaced open- ,7

ings formed in said adjusting brace, a fitting can ried centrally ofsaid connecting bar including a locking pin adapted to selectivelyengage in one of said adjusting brace openings-for -ang ttlar adjustmentof said plow, aiorwardlyand outwardly extending end brace fixedlycarried by each of said side bars intermediate the lengtl'i' 'ofi' thelatter, the forward" ends of said end braces being .pivotally connectedto-the divergent ends of said plow adjacent the lower edge thereof, an

end adjusting brace pivotally connected to each end of said plowadjacent the top edge thereof and extending downwardly and rearwardlytherefrom, a plurality of spaced openings formed in each of said endadjustin braces, and a locking pin carried by each of said end bracesadapted to selectively engage in said end adjusting brace openings.
